How do I start writing a blog?

How do I start? What if it sounds lame? Have these views been already expressed in boring detail by every other blogger? Am I too controversial? Too arrogant? or so boring as to have no views? Am I using the corrrect phrases? Am I grammatically correct? I am not an expert on anything so am I providing value?

I should be reading How to write a Better Blog
or begin with How to Write a Blog

How did I get into this? I am performance tuning my Oracle database and bored to death waiting for the queries to return. The results tell me that, I have long nights ahead. Look forward to more of this @#$$%$.
